Sunan an-Nasa'i 1319

Muhammad ibn al-Muthanna informed us; he said: Mu‘adh ibn Mu‘adh narrated to us; he said: Zuhayr narrated to us, from Abu Ishaq, from ‘Abd al-Rahman ibn al-Aswad, from al-Aswad and ‘Alqamah, from ‘Abdullah, who said: I saw the Messenger of Allah (peace and blessings be upon him) say the takbir at every lowering and rising, standing and sitting, and say the salutation to his right and left: “Peace be upon you, and the mercy of Allah; peace be upon you, and the mercy of Allah,” until the whiteness of his cheek could be seen. I saw Abu Bakr and ‘Umar (may Allah be pleased with them both) do that.
